UNITED STATES PATENT OFFICE.

REUBEN BITTER, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT l N PAPER-BOXES.

Specification forming part of Letters Patent No. 171,866, dated January 4, 1876; application filed September 18,1875.

' To all whom it may concern:

Be it known that I, REUBEN BITTER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Paper Boxes; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawing and t0 the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in the manufacture of paper boxes and covers without the use of paste, glue, or mucilage, whereby such boxes, when put together, cannot readily be taken apart, and also by reason of the peculiar configuration of the blanks I am enabled to manufacture boxes out of cheaper kinds of paper than is ordinarily used for the purpose.

The nature of my invention will be fully explained by reference to the'accompanying drawings, in which-- Figure 1 represents a box and cover, constructed according to my invention. Fig. 2 represents a plan view of the blank for forming the box and cover represented by Fig. 1. Fig. 3 represents a slight modification of the box and cover represented by Fig. 1, and Figs. 4 and 5 represent the blanks for forming the box and cover represented by Fig. 3.

In each of the views. similar letters of reference are employed to indicate corresponding parts wherever they occur.

A represents the blank from which the box is to be formed. This blank, according to the arrangement shown in Fig. 2, is cut from a single sheet of card-board. or other suitable.

- parallel with the edges thereof, and adapted, when the parts I) c d c are folded into a vertical position at right angles, to the part a, and the extensions 11 b and c c of the parts 12 c are folded at right angles to the said parts b c, to allow the curved retaining-pieces b b o o to be passed throughthe same, and when so passed through to be firmly retained by reason of the slots at e passing into the notches b c and firmly connecting the bottom a, front and back b 0, and sides d e, firmly together. This having been done the sides f f and front 1" of the top f are then folded at right angles to the top f, and the retaining-piecef folded around and passed through the slots f when the projecting portion f of the retainingpiece f will prevent the withdrawal of the retaining-piece f and hold the top or cover f in correct form. 9 g are locking-cords, provided with suitable extensions for insertion in the elongated cuts d 6; they protect from injury the curved. getaining-pieces b c after the latter have been passed through the cuts d-e. Figs. 4 and 5 represent blanks to form the box and cover represented by Fig. 3. In

this case the cover is formed separately from c d 6, connected together by curved retainingpieces b 0 passed through slots 01 e, in the manner and for the purpose described.

2. A box-top, consisting of the partsff f f connected together by notched extensions f passed through slots f", in the manner and for the purpose described.

3. A box and top, consisting of the parts a b c d cff f f, the parts a b c d 6 being oonnected' together by retaining-pieces b 0 passed through slots 6 d, and the parts f f' f",

by means of notched extensions f passed through slots f", in the manner and for the purpose described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

REUBEN BITTER.
